I can run the GUI i created but i am having difficulties when i press the calculate button. Everything works fine and the graph appears however an extra empty figure window is also appearing. I am new to matlab so i am unsure how to resolve the problem. Also I would like the x grid to be visible upon running the GUI (the inital graph should have the x grid on so it resembles strips of wood in my case) but i cannot figure out how to do this. Once i run my GUI and press calculate the grid lines show up but they dont upon initally opening running the GUI
any help is appreciated! thank you
